Apex: ImportError: cannot import name rnn_compat

When I import apex after the installation (finished with success) I get this error:

Are you using apex as your working directory?
If so, could you change the wdir and try to import apex again?

[davidenitti]

this is not the problem, but /homedir/.local/lib/python2.7/site-packages/apex/amp/rnn_compat.py is there

[ptrblck]

I could reproduce this error using Python 2.7.15 and as stated in the docs, we only support Python >=3.
Would it be possible for you to use a newer Python version?

[davidenitti]

oh right, it might be this the problem.
thanks I'll check

Did updating python fix the issue? Can we close this?

[mcarilli]

Please reopen if the problem continues with python 3+.

The solution for me is
import rnn_compat
(instead of from . import rnn_compat)
